Statins, including Pfizer Inc.’s Lipitor, are among the most prescribed drug in the world, and are currently routinely taken by millions of Americans. They are indicated for people with high blood pressure and/or high cholesterol, and have been shown to significantly reduce the risk of heart disease, heart attack, and stroke in this population. Yet the FDA has just issued new warnings concerning potential side effects: elevated blood sugar, which is a risk factor for developing type 2 diabetes, and cognitive impairment such as memory loss.

His results are reported in Science Translational Medicine.
